Connected treadle after fixing (7)
I believe the answer is:
'connected' is the definition.
(similar in meaning)
'treadle after fixing' is the wordplay.
'after fixing' is an anagram indicator.
'treadle' anagrammed gives 'RELATED'.
(Other definitions for related that I've seen before include "Kindred" , "Told (a story etc)" , "Having family links" , "As siblings obviously are" , "Like family members" .)
